Field Detail hashCode protected int hashCode(Code) The hashCode. keyAsObject protected Object keyAsObject(Code) The key as an Object. Constructor Detail SingleFieldIdentity protected SingleFieldIdentity(Class pcClass)(Code) Constructor with target class. Parameters:   pcClass - the class of the target SingleFieldIdentity public SingleFieldIdentity()(Code) Constructor only for Externalizable. Method Detail assertKeyNotNull protected void assertKeyNotNull(Object key)(Code) Assert that the key is not null. Throw a JDONullIdentityException if the given key is null. createKeyAsObject protected Object createKeyAsObject()(Code) Create the key as an Object. the key as an Object; equals public boolean equals(Object obj)(Code) Check the class and class name and object type. If restored from serialization, class will be null so compare class name. Parameters:   obj - the other object true if the class or class name is the same getKeyAsObject public synchronized Object getKeyAsObject()(Code) Return the key as an Object. The method is synchronized to avoid race conditions in multi-threaded environments. the key as an Object. getTargetClass public Class getTargetClass()(Code) Return the target class. the target class. since:    2.0 getTargetClassName public String getTargetClassName()(Code) Return the target class name. the target class name. hashClassName protected int hashClassName()(Code) Return the hash code of the class name. the hash code of the class name hashCode public int hashCode()(Code) Return the cached hash code. the cached hash code. readExternal public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException(Code) Read from the input stream. Creates a new instance with the target class name set. Parameters:   in - Input setKeyAsObject protected void setKeyAsObject(Object key)(Code) Set the given key as the key for this instance. Compute the hash code for the instance. writeExternal public void writeExternal(ObjectOutput out) throws IOException(Code) Write to the output stream.
